Minami lives happily with her husband and father-in-law. However, recently, due to being busy with work, her husband often comes home late, or even doesn't come home at all. One time, Minami accidentally dropped a glass of water and cut her hand. Her father-in-law immediately came to suck on her finger to help the wound heal faster. The physical contact with his daughter-in-law aroused his long-unused manhood, making him erect! Today is the wedding anniversary of the couple, Minami prepared a special meal, but she didn't eat and waited for her husband to return. However, he texted that he couldn't come back. Just then, her father-in-law arrived, so since her husband couldn't make it, she invited him to join the meal. Feeling lonely, she talked and shared her feelings with someone, so Minami drank a lot. She got drunk and fell asleep. Her father-in-law then carried her to his room and took advantage of her body despite her weak resistance. He licked and sucked all over her body, sucking up every drop of sweat and every drop of her arousal! After that incident, her father-in-law repeatedly engaged in this perverted act with Minami. She didn't like it, but for some reason, her body didn't resist. Every time he used his tongue to explore her body, her arousal flowed out, and her body gradually belonged completely to her father-in-law...
